-----------------
confirmed, also here a iconv.dll-issue (missing iconv.dll); and also
confirmed that it worked a month or so ago.
closer look at the error message and the used dependencies:
winGRASS 7.4.2 is now compiled against GDAL: 2.3.2 and PROJ.4: 5.2.0
when I tried a month or so ago, winGRASS was compiled against GDAL 2.0.X (or
similar) and PROJ.4 4.9. (or similar).
it seems there could be a dll mismatch between old and new dependencies
versions; hence the iconv.dll issue.
